Toyota and Honda recently started testing a fuel-cell bus designed as a mobile power source for disaster relief. Now Nissan has driven out an emergency response vehicle based on its Leaf electric car that will also provide emergency power.

Scientists have estimated the total amount of matter in the universe using a more precise method. By calculating the mass of hundreds of galaxy clusters, the team found that matter makes up around a third of the contents of the universe.

Bike headlights are now so bright that they can dazzle motorists, potentially causing those drivers to run into the cyclists using them. The Farina, however, is made to be bright without being blinding – plus it has some other nifty features.

Heart attack patients often need replacements for damaged arteries. In a new proof-of-concept study, scientists knitted a prototype graft out of hybrid synthetic and biological yarn, helping the patients own cells grow and repair the artery.

British company Samad Aerospace has unveiled a very unique VTOL aircraft design. The long-range, high-speed Q-Starling uses modified helicopter turbine engines to power turbojet thrusters as well as to charge the battery on an electric VTOL system.

A Yale team has developed a new “robotic fabric” that can change its shape and stiffness on demand or by sensing its environment. The material could one day be used in high-tech clothing, tents that set themselves up, or robotic parachutes.

In a wonderful case of blending an ancient therapy with modern tech, scientists gene edited the Leishmania major parasite to limit its infectivity. This allows the parasite to be given to patients in a vaccine, creating immunity without causing disease.

When surgery is performed on infants in utero, they're often born without any scars. This comes thanks to a special quality of their skin which scientists now believe could be replicated in adults, potentially leading to scar-free wound treatments.

Having tested out its aircraft in Dubai, Singapore, Helsinki and Germany, Volocopter is now turning its attention to Japan through a new agreement with Japan Airlines, and is preparing for a commercial launch in the country within a few years.

Italy's Aznom is preparing to branch out into small series car production with what it's calling the world's first all-terrain "hyper-limousine." The colossal Palladium promises huge power, dynamic handling, serious off-road chops and total luxury.

The UAE has outlined a vision to become just the fourth nation to land on the Moon by announcing plans to launch an Emirati-built rover by 2024, with mission planners hoping to gain a number of unique scientific insights about the natural satellite.

ZeroAvia says it completed the world's first hydrogen-fuel-cell powered flight of a commercial-grade aircraft when a modified Piper M-class six-seater plane took off from its facility in England, and completed a full-pattern circuit before landing.
